JAMES F. MOELROY, OF ALBANY, NEW YORK, ASSIGNOR TO CONSOLIDATED OAR-HEATING COMPANY, OF ALBANY, NEW YORK.

ELECTRIC RADiATOR.

SPECIFICATION forming part of Letters Patent No. 717,442, dated December 3 1902- Application filed January 16, 1896. Serial No. 575.797. (N0 model.)

To aZZ whom it may concern:

Be it known that I, JAMES F. MOELROY, a citizen of the United States, residing in the city and county of Albany,State of New York,

have invented a new and usefullmprovement in Electric Radiators, of which the following is a specification.

My invention relates to improvements in electrical heating devices; and the object of [O my invention is to produce an electric radiator which may be attached to the riser of a car-seat connected up in such a manner that there shall be a circulation of air between the back of the radiator and the riser and so ad-,

['5 justed that the front plate may be removed without interfering with the wire and the whole radiator placed in position very quickly and which will occupy a very limited space within the car. I attain this object by means of the mechanism illustrated in the accompanying drawings, in which-- Figure 1 is a front elevation. Fig. 2 is a front elevation with the enveloping case removed. Fig. 3 is a section along the line 3 3 on Fig. 2. Fig. 4 is a plan of the under side of the upper portion of the case-plate A. Fig. 5 isa cross-section along the line 1 1 on Fig. 1. Fig. 6 is a section along the line 2 2 on Fig. 1. Fig. 7 is an end elevation. Fig.

0 8 is an end .elevation of the enveloping case. Fig. 9 is an end elevation of the rear plate. Fig. 10 is a detail view of the hanger H. Fig. 11 is a modified form of construction of my radiator, and Fig. 12 is a modified form of said radiator.

Similar characters refer to similar parts throughout the several views.

The plate P, forming the back of my radiator, is curved or bent toward the top in such a manner as to form an outwardly-projecting concave portion at the top of the radiator, as shown in sections Figs. 5 and 6. of suitable bolts or screws 19 19, arranged toward the upper'portion of the plate P, I fasten the plate to the riser R of a car-seat, usually placing two bolts or screws, one near each end of the plate; I arrange bosses p on the rear of the plate P, which tend to keep the plate P'from contact with the riser By means.

R, leaving an air-space between the plate and so the riser.

On the upper surface of the curved or bent portion, on that part which is convex, I place the upwardly-projecting lugs L L, usually three in number. To the plate P, I suspend the resistance carrying core 0, which is usually of porcelain, mounted on a rod rand carrying a coiled wire W,by means of a hanger H at each end of the radiator. The hanger H is provided with slotted openings h h, which come in contact with the bolts J J, eX- tending into the plate P, in this manner sup porting the hanger and allowing for the longitudinal motion of the hanger occasioned by the expansion and contraction of thecore 5 O. The hanger carries a projecting piece H, through which is an opening 0", usually squared to admit of the passage of the rod r, carrying the core C. One end of the rod '1' has a nut N thereon, the other end a rigid head M, thus allowing for the rod to be drawn up tightly after the end to which the nut may be fitted is passed through the hanger and the nut secured thereon.

Attached to the end of the plate P, I arrange a block S, carrying an insulated disk D, through which the Wire W passes into the radiator and connected to the post T. The enveloping case is provided with a portion A at the top, which has a series of openings or a near the riser R, with which it comes in contact, forming a cover for the radiator. The under surface of the portion A of the enveloping case has a downwardly-projecting lug Z, adapted to engage with the lug L on the plate P, as shown in Figs. 5 and 6. The front of the enveloping case is provided near its up per portion with a series of openings 0 O to allow for the emission of heat and has an outwardly-projecting convex portion K nearer the bottom and surrounding the coiled resistance W. Along the bottom of the case there are a series of openings U, through which the air passes for the purpose of being heated and to come in contact with the resistance-wire W.

Near the loweredge of the front of the enveloping case I arrange openings for the passage of a bolt orscrewV,which passes through, similar openings in the lower portion of the plate P, said bolts V finding lodgment in the riser R a short distance above the floor of the car.

In putting my heater in position I first secure the porcelain core, with its resistancecarrying Wire, upon the hanger H, and,-attaching plate P to the riser by means of the upper bolts 19, I place the hanger in position on the bolts J and then place the enveloping case in position, the lugs Z in contact with the lugs L, and force down the lower portion of the case and insert the bolts V, passing through the plate P into the riser. It will be noticed that in this manner the heater is quickly connected up. The enveloping case may be removed Without interfering with the wires for the purpose of making repairs. As thus arranged a current of air will pass between the riser and the bottom of the radiator, preventing injury to the riser from heat, the air taking the direction shown by arrows in Figs. 5 and 6. A current of air will also pass through the radiator from the bottom out at the top, coming in contact in its passage with theheated coils.

Figs. 11 and 12 are modifications of the structure, but employ the same principles of construction. Fig. 11 shows a seat without a riser, in which case the heater is held in position by means of suitable straps Y. It will be noticed, however, that in all of the structures there is an interlocking of the front and back of the case at the top, so that one bolt or set of bolts or screws at the bottom hold the two in place. In Fig. 12 a foot-rest is made by casting the back and rest in one piece, it being joined by a lug and recess to the front plate, as at 4;.

It will be noticed that the front and rest are of one piece in Figs. 5 and 6, and Fig. 12 is an alternative construction.

What I claim as my invention, and desire to secure by Letters Patent, is

In a heater, a concavo-convex plate com prising the rear portion of the resistance-envelopin g casing, adapted to be attached to the riser of a car-seat, the back of the casing spaced from its support, the front portion of said casing connected to said rear portion by engaging lugs and held at its lower edges by locking-bolts, a fiat portion extending from the concavo-convex portion of the rear casing forming an air-space therein, said flat portion having perforations adjacent to the riser of the car-seat, substantially as described.
